HYDROCARBO N-BURNER.

SPECIFICATION forming part of Letters Patent No. 499,968, dated June 20, 1893.

Application filed July 21, 1892.

steam, or with compressed air substituted for' steam.

It is the purpose of my invention to provide a simple and economical structure, so

[ organized that the several parts shall have a definite, fixed relation, one to the other, of such kind as to eifect the combination of the several gaseous ingredients in the best manner possible and their perfect consumption with the maximum heat, or light, obtainable. In the construction of burners of this type,

heretofore, the union of the parts has been usually effected by such constructions as to require the services of askilled laborer, or

: expert, in adjusting the several parts in order to secure the proper relation and the most efficient (so-operation of the said parts, in action. In all burners of this type,a slight displacement of the steam-pipe, or fluid pipe, or

0 of the terminal of the oil-pipe, is sufficient to defeat the purposes in View, and even when this defect of arrangement is so small asto be practically unnoticeable, the proper action of the combined parts will be, under the most 5 favorable circumstances, so defective. as to render the burner essentially Worthless.

It is the main purpose of my invention to provide a novel and simple construction whereby these objections shall be avoided, and

40 whereby the assemblage of the parts and their permanent union may be effected without the necessity of a final adjustment by experts, each burner having, when it leaves the factory, a perfect adjustment in all its parts,

5 which is incapable of subsequent alteration.

.It is my purpose, also, to simplify the construction and reduce the number of the parts, to avoid the use of needle-valves in the burner, and thereby obviate the gumming' and carbonizing of the seating portions, and to reduce $erial No. 440,788. (No model.)

the expense of manufacture of this class of burners in a material degree.

My invention consists, to these ends, in the several novel features of construction and new combinations of parts hereinafter fully set forth and then more definitely pointed out in the claims annexed to this specification.

- To enable others skilled in'the art to understand and to make, construct and use my said invention, I will now describethe same in dc- 6o tail, referring, for this purpose, to the accompanying drawings, in which-- Figure 1 is a longitudinal section taken in the axial line of a burner constructed in accordance with my invention. Fig. 2 is a transverse section in the line 2-2, Fig. 1. Fig. 3 is an end elevation of the burner shown in Fig. 1, the point of view being at the lefthand end. Fig. 4 is a detail View of the spider-support at the end of the burner.

In the said drawings the reference-numeral 1 indicates the casing of the burner, the main part thereof being cylindrical and of such dimensions that its interior diameter shall exceed the exterior diameter of the concentric 7 steam-pipe sufficiently to provide an annular, intermediate space. Within this cylindrical portion is arranged the steam-pipe or fluid pipe 2, concentric, or substantially so, with the burner. This pipe is preferably a threeeighths inch gas-pipe, though I am not restricted to any special diameter thereof.

From the rear end of the burner to a point ,between its middle audits forward extremity, the body portion is of substantially equal diameter, or cylindrical, but at a short distance from its combustion-end it contracts to an open mouth 3, having a diameter, in the present instance, of about three-fourths of an inch, the contracted extremity having sub- 0 stantially the form of a frustum of a right cone, its axis being co-incident-with, and forming a continuation of, the axis of the cylindrical portion, or body. A little in rear of the'point where the contraction begins, is 10- 5 cated a spider-shaped partition, or skeletonframe, composed of a plurality, usually three, of radial lugs, or extensions 4, uniting at equal intervals with a central boss 5. These parts may be, and preferably are, integral with the mo burner, the whole'being cast in one piece; but they may be of separate constrnctionyif preferred, the spider being permanently united with the burner in any suitable'manner. The boss 5, which is concentric, or nearly so, with the burner, projects some distanceinlrearof the point ofattachment, orunion, of-itsdugs 4 with the burner, and is providedwith a recess 6,which is drilled concentric with the inner face of the body of the burner, the fortward end of said recess being contracted, ortapered,'to

a small opening concentric with the recess 5. The interior. of the latter is tapped to provide a female thread for the'attetchmentbfthe ehd 5 from the rear. Asecond pointof supportfor said, zpipe' is "provided bytrneans-otl aI spiderframe, consistingof acentralring Z .witllthree,
